πŸ”— Bacon's Cipher

πŸ”— Cryptography πŸ”— Cryptography/Computer science

Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605. A message is concealed in the presentation of text, rather than its content. Bacon cipher is categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces).

πŸ”— Laniakea Supercluster

πŸ”— Astronomy πŸ”— Astronomy/Astronomical objects

The Laniakea Supercluster (; Hawaiian for "open skies" or "immense heaven") is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies. It was defined in September 2014, when a group of astronomers including R. Brent Tully of the University of Hawaiʻi, Hélène Courtois of the University of Lyon, Yehuda Hoffman of the Hebrew University of Jerusalem, and Daniel Pomarède of CEA Université Paris-Saclay published a new way of defining superclusters according to the relative velocities of galaxies. The new definition of the local supercluster subsumes the prior defined local supercluster, the Virgo Supercluster, as an appendage.

Follow-up studies suggest that the Laniakea Supercluster is not gravitationally bound; it will disperse rather than continue to maintain itself as an overdensity relative to surrounding areas.

πŸ”— Tragedy of the Anticommons

πŸ”— Environment πŸ”— Economics πŸ”— Law πŸ”— Anthropology πŸ”— Sociology πŸ”— Game theory

The tragedy of the anticommons is a type of coordination breakdown, in which a commons does not emerge, even when general access to resources or infrastructure would be a social good. It is a mirror-image of the older concept of tragedy of the commons, in which numerous rights holders' combined use exceeds the capacity of a resource and depletes or destroys it. The "tragedy of the anticommons" covers a range of coordination failures, including patent thickets and submarine patents. Overcoming these breakdowns can be difficult, but there are assorted means, including eminent domain, laches, patent pools, or other licensing organizations.

The term originally appeared in Michael Heller's 1998 article of the same name and is the thesis of his 2008 book. The model was formalized by James M. Buchanan and Yong Yoon. In a 1998 Science article, Heller and Rebecca S. Eisenberg, while not disputing the role of patents in general in motivating invention and disclosure, argue that biomedical research was one of several key areas where competing patent rights could actually prevent useful and affordable products from reaching the marketplace.

Hybrid Insect Micro-Electro-Mechanical Systems (HI-MEMS) is a project of DARPA, a unit of the United States Department of Defense. Created in 2006, the unit's goal is the creation of tightly coupled machine-insect interfaces by placing micro-mechanical systems inside the insects during the early stages of metamorphosis. After implantation, the "insect cyborgs" could be controlled by sending electrical impulses to their muscles. The primary application is surveillance. The project was created with the ultimate goal of delivering an insect within 5 meters of a target located 100 meters away from its starting point. In 2008, a team from the University of Michigan demonstrated a cyborg unicorn beetle at an academic conference in Tucson, Arizona. The beetle was able to take off and land, turn left or right, and demonstrate other flight behaviors. Researchers at Cornell University demonstrated the successful implantation of electronic probes into tobacco hornworms in the pupal stage.

πŸ”— Physiognomy

πŸ”— Psychology πŸ”— History of Science πŸ”— Occult

Physiognomy (from the Greek φύσις, 'physis', meaning "nature", and 'gnomon', meaning "judge" or "interpreter") is the practice of assessing a person's character or personality from their outer appearanceβ€”especially the face. The term can also refer to the general appearance of a person, object, or terrain without reference to its implied characteristicsβ€”as in the physiognomy of an individual plant (see plant life-form) or of a plant community (see vegetation).

Physiognomy as a practice meets the contemporary definition of pseudoscience and it is so regarded among academic circles because of its unsupported claims; popular belief in the practice of physiognomy is nonetheless still widespread and modern advances in artificial intelligence have sparked renewed interest in the field of study. The practice was well-accepted by ancient Greek philosophers, but fell into disrepute in the Middle Ages while practised by vagabonds and mountebanks. It revived and was popularised by Johann Kaspar Lavater, before falling from favor in the late 19th century. Physiognomy in the 19th century is particularly noted as a basis for scientific racism. Physiognomy as it is understood today is a subject of renewed scientific interest, especially as it relates to machine learning and facial recognition technologyThe main interest for scientists today are the risks, including privacy concerns, of physiognomy in the context of facial recognition algorithms.

Physiognomy is sometimes referred to as 'anthroposcopy', a term originating in the 19th century.

πŸ”— Omission of New Zealand from Maps

πŸ”— New Zealand πŸ”— Maps

New Zealand has often been omitted from maps of the world, which has caught the attention of New Zealanders. It is considered that this is because of the widespread use of the Mercator projection, a map projection putting Europe in the center which leaves New Zealand in the bottom right-hand corner of maps, sometimes making it go overlooked by mapmakers, easily removed by an accidental crop, or simply not added for convenience, ignorance or laziness.

New Zealand has been excluded from maps at the National Museum of Natural History in Washington, D.C. in the United States, in IKEA stores, on the map of the board games Pandemic and Risk, on the map of the 2014 Nuclear Security Summit in which Prime Minister of New Zealand John Key participated, at a world map seal at the United Nations Office at Geneva in Switzerland, on the newspaper Daily Mail, on Government Executive's newsletter Defense One, on the magazine Forbes, on the digital media platform Mashable, on the Pyongyang International Airport in North Korea and on the logo of the Flat Earth Society. It was also excluded from maps promoting the 2015 Rugby World Cup even though New Zealand was the then world champion.

This recurrent occurrence has become a meme for New Zealanders. There is a community on Tumblr titled World Maps Without New Zealand and a Reddit community known as r/MapsWithoutNZ both focused on this issue with 10,000 and 30,000 members respectively as of 2017. In 2019, a user in r/MapsWithoutNZ noticed that a map, "BJΓ–RKSTA world map", on sale for 30 dollars at an IKEA store on Washington, D.C., did not portray New Zealand. Subsequently, IKEA apologized and removed the product from its stores. On Reddit, there also are communities about the omission of Flevoland in the Netherlands, Hawaii in the United States and Tasmania in Australia from world maps.

The New Zealand Government has acknowledged this phenomenon, and it features a map of the world in which the country is deliberately not included on the 404 error page of its official website; the page states that "something's missing". Furthermore, in 2018, a tourism campaign video was published in which the Prime Minister of New Zealand Jacinda Ardern and the New Zealander actor and comedian Rhys Darby discussed why New Zealand was being left off world maps. On the video, Darby jokingly said that it was the result of a conspiracy against New Zealand. The video promoted the hashtag #getnzonthemap.

πŸ”— Josephson Voltage Standard

πŸ”— Electronics

A Josephson voltage standard is a complex system that uses a superconducting integrated circuit chip operating at a temperature of 4Β K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement in 1990, is the basis for voltage standards around the world.

πŸ”— Trancitor

πŸ”— Electronics πŸ”— Electrical engineering

The trancitor as the combined word of a "transfer-capacitor" is to be considered as another active-device category besides the transistor as a "transfer-resistor". As observed in the table shown, four kinds of active devices are theoretically deduced. Among them, trancitors are missing to be the third and fourth kinds, whereas transistors, such as bipolar junction transistor (BJT) and field-effect transistor (FET), were already invented as the first and second kinds, respectively. Unlike the transistor switching the current at its output (i.e., current source), the trancitor transfers its input to the voltage output (i.e., voltage source), so an inverse relationship with each other.
